Dissolved Oxygen (DO) Meter

• Waterproof, dustproof and it even floats!
• Input salinity and pressure values manually. Meter automatically calculates the offset value for increased accuracy.
• Dual display shows dissolved oxygen, in mg/L (ppm) or % saturation, and temperature.
• °C/°F selectable.
• Expanded memory stores up to 50 DO/temperature readings.
• Real-time clock time/date stamps stored readings and calibration data.
• Salinity correction range is from 0.0 to 50.0 ppt.
• Barometric correction range is from 500 to 1499 mm Hg(66.6 to 199.9 kPa).
• Independent 100% and zero adjustment calibration for high accuracy over the full meter range.
• Automatic temperature compensation from 0 to 50°C (operating temp. range).
• Easy-to-service low maintenance probe. Replaceable membrane cap assembly makes probe maintenance hassle-free. Simply fill cap with electrolyte solution and screw on.
• Very low drift probe for enhanced stability and repeatability.
• Data hold, ready indicator and automatic shut-off features.
• Displays electrode diagnostics: slope, zero offset and millivolt values.
• Adjustable backlit display for taking readings in dark areas.
• Dimensions: Meter 7.5”L x 3.5”W x 1.75”H, Probe 6.8”L x 1.3”dia.
• Power: 4 x 1.5V AAA batteries for >100 hours of continuous use.
• Warranty: 3 years on meter only.
• All meters are supplied with galvanic probe, electrolyte solution, batteries and operating instructions.
• DO meter kit includes 500 ml of electrolyte solution, 5 replacement membranes, three rinse bottles and hard carrying case with space for your meter and probe.
